0.4.0

Kabanero-operator release 0.4.0 has been tested with the following components:

• OpenShift Container Platform (OCP) 4.2
• OpenShift Service Mesh 1.0.2
• OpenShift Serverless Operator 1.1.0
• OpenShift Pipelines Operator 0.7
• Knative Eventing Operator 0.9
• Knative Sources 0.9
• Appsody Operator 0.2.2
• Eclipse Che Operator 7.3.1

There are a few architectural changes in version 0.4.0 of the kabanero operator:

• The collection controller has been separated into its own pod/container with its own service account. This will allow us flexibility in targeting a separate build or deploy namespace in a future release.
• An admission webhook is added as a separate pod/container.
• The collection index and pipeline resources retrieved from Github are cached locally after they are retrieved. The cache is maintained using etags. This should reduce the amount of traffic to Github when multiple collections use the same pipeline resources.

The install script attached to the release can be used to configure your OCP cluster for Kabanero. It can also be used to upgrade an existing Kabanero 0.3.1 - 0.3.x installation to the 0.4.0 level.
